Outline of Final Research Achievements |
To identify oral cancer-associated microRNAs (miRNA), samples (tumor and normal tissue) were analyzed with microRNA microarray. Candidate miRNAs with expression levels that were significantly altered in oral cancer samples or selected from a literature review were identified as Onco-miRNA or Tumor-suppressor miRNA. We found that miR-205-5p functions as a tumor suppressor in oral squamous cell carcinoma (OSCC), that miR-205-5p directly regulates TIMP-2 expression, and that miR-205-5p suppresses pro-MMP-2’s activation by regulating the TIMP-2 expression in OSCC cells. Thus, it may be possible to use miR-205-5p to regulate specific tumor-progressive genes as a novel therapeutic approach to treating OSCC.
